Joint derangements are about 80% of all orthopedic problems. Derangements are when a joint isn't sitting properly, leading to pain, stiffness, tightness, and so on. They are usually rapidly reversible! Unfortunately, people are often given structural diagnoses instead (here, it's an AC sprain) or told they have a muscle or tendon problem.

Since joint derangements comprise the LARGE majority of orthopedic problems, McKenzie experts are trained to look for them first. If a joint derangement is found, we use repeated movements to restore joint alignment. This patient had shoulder pain and limited movement following a car accident. One movement fixes her symptoms (bringing her arm across her body) - and one movement worsens her symptoms (bringing her arm back away from her body). McKenzie experts are trained to find WHICH movement is best for you and use that one movement as the treatment approach. -- Laura
